6- or 7-channels? / 2.4 GHz or not?

Hi, I am in the planning face of building an EasyStar with ArduPilot, and I need to buy an transmitter.I have been thinking of buying a Futuba 6EXP, 6EXG or 7C.(Yes, I know about the cheap Turnigy, so now need to mention it.)But which should i go for, 7C is much more expansive, so do i really need 7-channels to get ArduPilot working properly?And if 6-channels is enough, should I by a transmitter with 2.4 GHz or not?Hope somebody can give me some good advice.

  • Well, anyway, to begin with I'm going to learn to fly the plane, so that's probably going to take some time.
    But then, I will start playing with ArduPilot, and see how fare I can come with this transmitter. Maybe there is another way to get the different modes to work?

    After reading the manual Nathaniel provided, I doubt it has a 3 way switch.
    Still, in this manual of the 2.4 GHz version I found, (mine is FM,) there is a mention of a "SW-3 FLT MODE" switch, which "allows you to choose three different "flight condition modes"-an advanced programming function.".

    The 2.4 GHz and the FM seams to be different in some ways, even if they're name is the same.

    When I get the transmitter I will get back to this topic and write for sure if there is a 3 way switch or not.
  • Tanks for the replays, I got a great offer on a Hitec Optic 6 Sport for 31$, so I bought it.
    It hasn't got 2.4 GHz so that's why is was so cheap.
    But I thought it would be a good beginner radio, and I can always upgrade to something better later.
  • How is the quality of Hitec compared to Futuba?
    And how is it possible to have a 3 way switch, wouldn't the transmitter then need 7-channels? Or is the 3 way one channel?

    The Turnigy 9x looks like a good choice, but is seams like they never have them in stock, and when, they are ripped away long before I get the chance to even look at it.
  • I don't know how price are in the states, but here in Norway 7C is about 110$ cheaper than DX7, and Futaba 6EXG is about 195$ cheaper than 7C.

    (6EXG costs about 300$ including batteries here.)

    Are these prices really worth it?

    Two flight modes, does that mean manual flight + 2 modes, or manual flight + an other mode?

    Of the list you've given, the 2.4GHz 7C is probably your best bet. Neither of the 6* radios seems to have a three-way switch, which limits you to at most two flight modes.

    You might want to consider the Spektrum DX7 as an alternative. It's a better controller in many ways, though DSM2 is arguably a less robust communications link than FASST.
